YH—ITM中数据缓冲部件的设计与实现

The Design and Implementation of Data Buffer Units in the YH ITM

智能工具机ＹＨ－ＩＴＭ是一个基于ＲＩＳＣ、支持多种人工智能语言和传统Ｃ语言的通用智能计算机系统。数据缓冲部件ＤＢＵ是该系统中的一个重要组成部分。本文论述了ＤＢＵ的功能、结构、工作状态、对多处理机环境及对Ｐｒｏｌｏｇ的支持，以及对各类访问的处理。

The YH-ITM intelligent tool machine is an RISC-based general-purpose intelligent computer system which supports several AI languages and the tradi-tional C. Data buffer units(DBUS)are important components of the system. In this pa-per we describe the functions,architectures and working states of the DBUS and theirsupport to multiprocessor environments,Prolog and various accesses handling.
